app :: (a -> b) -> a -> b infixl 1 Source
Only useful since it is left associated with a precedence of 1, unlike $, which is right associative.
e.g.
someFunction
`appMatrixLen` m
`appVectorLen` v
`app` other
`app` arguments
`app` go here
One could also write:
(someFunction
`appMatrixLen` m
`appVectorLen` v)
other
arguments
(go here)
appMatrixRaw :: Storable a => (Ptr a -> b) -> Matrix a -> b infixl 1 Source
unsafeMatrixToVector :: Matrix a -> Vector a Source
This will disregard the order of the matrix, and simply return it as-is.
If the order of the matrix is RowMajor, this function is identical to flatten.
unsafeMatrixToForeignPtr :: Storable a => Matrix a -> (ForeignPtr a, Int) Source
